The dark oval line above your new belly button after a tummy tuck could be due to a few reasons: 1. Post-surgical Hyperpigmentation: This is a common side effect of surgery where the skin darkens in the area of the incision. This can occur as a response to inflammation caused by surgery. 2. Scar Tissue: The dark line could be scar tissue forming after the surgery. This can sometimes appear darker than the surrounding skin. 3. Healing Process: It may be part of the healing process, where blood vessels are healing and new skin is forming. 4. Post-Inflammatory Hyperpigmentation (PIH): This occurs when a wound or irritation, like a surgical incision, causes an increase in skin pigment production. 5. Keloid or Hypertrophic Scar: These are thick, raised scars that can form after surgery and can be darker than the surrounding skin. 6. Suture Reaction: If the dark line is exactly where the sutures were placed, it could be a reaction to the sutures. The rough, dry skin could be due to the healing process and formation of new skin. It's important to keep the area moisturized and protected from the sun, as it can exacerbate the darkening. However, it's highly recommended that you consult with your surgeon or a dermatologist to get an accurate diagnosis and appropriate treatment. They may suggest treatments such as creams, laser treatments, or other procedures to help lighten the area, if necessary.
